Abstract Text:
We describe the current capabilities and applications of the HiFi
multi-fluid modeling framework – a simulation tool for model development, experiment design, and fundamental physics studies. Recent development and applications of HiFi have been led by the innovative confinement concept (ICC)-focused Plasma Science and Innovation Center, though its user base now includes the solar and greater astrophysics communities. HiFi is a two- and three- dimensional implicit high order finite (spectral) element code with finite element spatial representation in all dimensions, flexible multi-block computational domain, generic flux-source form for the partial differential equations it can solve, and multiple boundary condition options that can be implemented in its framework. HiFi’s user-interface is designed to be readily usable by a computationally-literate graduate student. That, together with the wide applicability of the framework to various physical
systems, makes it particularly attractive to small-scale research
teams characteristic of the ICC environment. Here, we will describe
several recent ICC-relevant applications, such as magnetic reconnection and relaxation of spheromaks in varied closed domains, FRC liner compression, and two-fluid plasma-neutral modeling of FRC translation. Future planned development and applications will also be discussed.
